I think a lot of it has to do with the personality of the child. My daughter is very cuddly and affectionate with me. Hot and cold with DH. If she's uncomfortable or tired, she wants to be with me. No, make that on
me. She loves to be on my lap if I am sitting down.
The coolest thing was about 3 weeks ago when she came up to me and hugged my knees and said "I love you, Mommy!"
She also is very snuggly in bed. Lately, when she's tired, and ready to go to sleep, she likes to have my arm around her. We've always done this, but now, if I don't have it just in the right place or if I try to move it away too soon, she'll grab my fingers and put my hand on her chest or her belly. It's so sweet.
DD also likes to hug the dogs. She's not into giving or receiving kisses much though and she's not too sure about affection from other kids her age (2).
She also can be affectionate when she nurses - sometimes she strokes my arms. (Most of the time she picks at her scabs though - eeew!)
